Things You Need To Know About Apple Swift Programming Language

As you all know that Apple recently made SWIFT programming language open source. Swift is a very powerful programming language. Swift is a modern programming language that is safe, fast and interactive. Writing Swift code is interactive and fun, and apps made in Swift runs a lot faster.

Introducing Swift 2

Swift has been refined from the ground up. It generates code across the board, both for release and debugs build.

The Swift compiler is also faster , even while adding new Fix-It suggestion as where you can use let instead of var. Comments can include Makdrown syntax to add rich text and embedded images that display in Xcode’s Quick Help. Swift Api is shown in a new assistant “header-like” view.

Error handling model

In Swift there is an advanced error handling model which provides clear,expensive syntax for catching and throwing errors. And  in Swift it’s also easy to create your own custom error types so you can describe error cases with clear and meaningful names. A new error model has also been designed to work seamlessly with NSError  and the Cocoa frameworks. Error handling codes now look like:-

“ func loadData() throws {}
Func test() {
Try loadData()
} catch {



To get access to the latest features you should always use the latest SDK, documentations, and API changes, but sometimes your apps need to run on older OS, therefore, Swift has built-in availability checking tool to make it easy to build the best possible app for each targeted OS version.

Syntax improvements

The new syntax feature let you write more expensive code while improving consistency across the languge.The SDKs have employed new Objective-C features such as generics and nullability annotation to make swift code even more cleaner and safe.

Open Source

Swift is developed in the open at, with source code, a bug tracker , mailing lists, and a regular development builds that are available for everyone. Swift is even made more amazing by the broad community of developers ,both inside and outside of Apple Inc. Swift supports both Mac and Linux.


The development of Swift programming language is a result of the latest research on programming languages, combined with decades of experience building Apple platforms. Named parameters are brought forward from Objective-C and are expressed in a clean syntax that makes APIs in Swift even easier to read and maintain. Inferred types make code cleaner and less prone to mistakes, while modules eliminate headers and provide namespaces. Memory is managed automatically, and you don’t even need to type semi-colons(;).

Fast and Powerful

From its earlier conception, swift was built to be fast. Using the incredibly high-performance LLVM compiler, Swift code is transformed into optimized native code that gets the most out of modern hardware.

The syntax and standard library have also been tuned to make the most obvious way to write your code in the best way.

Swift is a successor to both the C and Objective C languages. It includes low level primitives such as types, flow control, and operators.

So this is all about Swift programming language, Hope you liked it!!!
